The aim of this study was to give information for debate about the needs to adaptation the game rules in children´s volleyball. Only there is one change between international and children´s rules in Spain. We analysed data from the only championship played in Spain when it was allowed to play with “libero”. Results don´t show a positive dependence with one of the most important factors in the player’s development: continuity.
First tempo is other critical factor in the debate about early specialitation. There´s no a lot presence in this case, but it also show a positive dependence with continuity.
Other contextual factors like set match playing or the different match phase (serve or reception), are in relationship with continuity.
